How to get the data in comboBox C#

Question

I have a combo box and I populated it this way:

DataTable dt = new DataTable();

using (SQLiteConnection conn = connection.Conn)
{               
    using (SQLiteCommand cmd = new SQLiteCommand(conn))
    {
        cmd.CommandText = "select id, description from category";
        conn.Open();

        using (SQLiteDataAdapter da = new SQLiteDataAdapter(cmd))
        {
            da.Fill(dtChargeCodes);
            comboBox1.DataSource = dt;
            comboBox1.DisplayMember = "description";
            comboBox1.ValueMember = "id";
        }                                       
    }               
}

What I'm trying to achive is to get the data of the selected item in the comboBox but when I tried to display it using MessageBox.Show(comboBox1.SelectedItem.ToString()); what I get is the type System.Data.DataRowView. not the actual value of the field description in the table category. Please help... thanks.

Answer 1

Either use

comboBox1.SelectedText

or

((System.Data.DataRowView)(comboBox1.SelectedItem))["description"]

You may need to use the second method if you need to access the value in the SelectedIndexChanged event (see here)

Answer 2

Try this:

MessageBox.Show(comboBox1.SelectedValue);
